Contexte

 

Humanity is faced with major challenges related to global warming, energy supply and pollution, all posing a tremendous need for clean and renewable energy sources. Among them, kinetic energy available in ambient environment remains largely unused. For instance, vibrations resulting from movement of the human body, operation of industrial machinery and transport vehicles can all be harvested using piezoelectric materials.

Piezoelectric energy harvesting has been intensively investigated in recent years. However, to achieve a major breakthrough on the market further research is needed in the fields of device design and process development, which will enable high harvested power densities and low-cost manufacturing. Electroactive polymers emerged as a promising class of materials. They facilitate high figure-of-merit structures at low processing temperatures on flexible substrates.  

At LIST we have developed a technological platform able to process piezoelectric thin films via chemical methods. An important pillar is inkjet printing of materials, which enables direct patterning of piezoelectric structures. Using this approach the consumption of the starting precursors is reduced and several patterning steps can be omitted in the process, resulting in significant decrease of manufacturing costs.

 

Description

 

The trainee will use the existing knowledge on inkjet printing of polymer piezoelectrics and will work on new and innovative processing solutions. The work will consist of the following steps:

  • design of energy-harvesting structures
  • synthesis of inks
  • inkjet printing (jetting of the inks, control of interaction of the inks with the substrate, annealing)
  • microstructural and electromechanical characterization of the structures

Trainee will have the opportunity to perform multidisciplinary work in the state-of-the-art chemical laboratory, clean room and characterization facilities of LIST. He/she will have access to different processing techniques, such as inkjet printing and rapid thermal annealing, together with a number of characterization equipment, including scanning electron microscope, X-ray diffractometer, profilometer, spectrophotometer, ferroelectric and piezoelectric testers.
